APPARATUS FOR RAISING PILE FABRICS.

l '0 all whom it may concern:

Be it known that we, FRED SHAW and JOSEPH DUTTON, both subjects of theKing of Great Britain, and residing, respectively, at 14 Durnfordstreet, Middleton, in the county of Lancaster, and \Vyke House, WingateRoad, Hale, in the county of Chester, both in the country of England,have invented certain new and useful Improvements in Apparatus forRaising Pile F abrics, of which the following is a specification.

This invention relates to cross brushing machines for raising pilefabrics such for example as velvets, cords and the like, and has for itschief object to increase the efliciency and output of apparatus of thisclass.

In cross brushing machines as at present constructed it is customary toemploy a number of rows of rollers arranged one above the other, theupper row or rows of rollers constituting the brushing rollers and thelower row the tens'ioning rollers the fabric to be treated beingtraversed in a zigzag fashion over the brushing rollers and under thetensioning rollers, and subjected to a brushing operation by areciprocating brush which travels to and fro across the width of thefabric, one brush being em ployed in conjunction with each brushingroller. This arrangement necessitates a large number of working partsand a machine which covers a considerable amount of floor space,moreovera large amount of power is required to draw the fabric under andover the various sets of rollers.

According to this invention instead of applying a single brush to eachbrushing roller and employing a number of such rollers to complete thebrushing operation, the fabric. to be treated is traversed around arevolving drum and is subjected to a reciprocating brushing action in alateral direction by relative movement of the fabric and a series ofbrushes which surround or partly surround the drum. The latter may bemade of such a diameter as to accommodate a sufficient number of brushesto complete the brushing operation on one drum. Two or more of suchdrums may be placed one above the other in one machine and two or morepieces of fabric may be treated at the same time, or if desired thedrums may be made somewhat smaller in diameter and the fabric may betaken from one drum to another to Specification of Letters Patent.

is a front elevation and Fig. 2 an end ele ration of a machine providedwith two drums in accordance with this invention. Figs. 3 and 4c arediagrams of the brushes. Fig. 5 is an end view of the drum around whichthe brushes are arranged. Fig. 6 is a longitudinal section of part ofthe drum. Fig. 7 is a detached view showing the parts of the mechanismwhich exert a resilient pressure upon the backs of the brushes, and

Fig. 8 is a detached view of one of the brush holder end frames.

A indicates the revolving drum and B B indicate the brushes. Each of thebrushes B is supported at each end in a frame or holder Z) that isformed with a number of pockets 6 (Fig. 5) to receive the ends of thebrush backs and is secured to the adjacent end frame G of the machine.The brushes are detachably mounted in the afore said pockets and theends of each brush back are rabbeted or recessed at 6 (Figs. 3 and 4:)to enable the brushes to be adjusted for wear and to prevent the brushback from coming into contact with the fabric, the arrangement beingsuch that before the bristles are worn flush with the surface of thebrush the portion 72 of the brush back comes into contact with thepocket flange 72* (Fig. 8) and prevents further adjustment of the brush.Each brush is arranged to exert a yielding pressure upon the fabric bymeans of springs provided with regulating devices for controlling thepressure exerted by the springs. Any appropriate mechanical device maybe employed for effecting this purpose and in the example shown springcontrolled levers b are pivoted on studs 6 carried by brackets b thatare fixed to the brush holder frames 6 and each lever is attached to oneend of a torsion spring 6 that is connected at its opposite end to acollar Z2 supported on the stud b and secured thereto by a pin 6 Thiscollar may be formed with a number of radial holes for the reception ofthe aforesaid pin so that the collar may be turned in either directionthrough a revolution or portion. of a revolution and secured in itsadjusted position by the pin to slacken or tighten the spring accordingto the pressure to be exerted by the levers 71 upon the brush back.

In an alternative arrangement a blade spring extending along the brushback and provided with screw adjustment may be substituted for thedevice described. In the example shown the bristles B of the brushes areinserted in spaced rows as shown in Fig. 8 a row of bristles in onebrush coming opposite to a blank portion in the adjacent brush and eachblank portion is formed with an aperture Z) for allowing the escape offlock and lint. This construction is not however absolutely necessaryand the bristles may be otherwise arranged and the holes 6 be dispensedwith. In the example shown in the drawings two of the rotary drums A areplaced one above the other and each of these drums is reciprocated in anendwise direction while the brushes B remain stationary. For thispurpose each of the drums is slidably mounted. upon a square shaftu(Figs. 5 and 6) rotatably mounted in bearings a (Fig. 2) on the endframe C. These shafts are connected by a belt on the pulleys a (Fig. 1)and receive their motion from a main driving pulley a on a shaft a andstepped speed cones a a. Endwise motion is imparted to the drums A by alever a pivoted in a bracket a carried by the end frame C. This lever isslotted at a for the passage of the drum shafts and is connected bylinks a with a collar a (Figs. 5 and 6) rotatably mounted on a. bush (1,which supports the end of the drum A upon the square shaft. The collar(0 is retained in position by a plate a screwed to the drum A. The upperend of the lever is connected by a rod (0 (Fig. l) with a crankedportion of a shaft a driven by bevel gearing a. from a shaft a which isconnected with the main driving shaft a by a belt on the pulleys a (Fig.1). In order to cause the fabric to follow the movement of the drum thelatter is formed or pro-- vided with a roughened or other appropriatesurface which will prevent the fabric from slipping thereon, for exampleit may be covered with a material resembling card clothing which is usedin ordinary cotton carding engines, but with the teeth of the wire pinsprojecting above the surface of the clothing to a su iicient extent toengage with and grip the adjacent surface of the fabric as it is passedthrough the machine.

In order to prevent the fabric from creas ing longitudinally through thereciprocating movement that is imparted thereto in a lateral directionthe fabric is fed to the drum through a group of rollers D. Theserollers are carried between end frames cl (Figs. 1 and 2) which areslidably mounted upon a square shaft (Z carried by brackets (Z (Fig. 1)secured to the machine frame 0 and each end frame (Z at one end of themachine is connected by a link (Z with an arm projecting from theaforesaid lever at so that the movement of the latter causes each groupof rollers to move in an endwise di rection with its drum. The aforesaidgroup of rollers in addition to preventing the aforesaid longitudinalcreasing of the fabric also serve to retain the fabric in contact withthe surface of the drum. The fabric after being treated by the lowerdrum may be taken to the upper drum to have the brushing operationcompleted and in this case the upper drum may be rotated slightly fasterthan the lower drum to maintain a tension upon the fabric, or'if desireda separate piece of fabric may be treated by each drum. When the fabricis taken from one drum to the other, the two drums reciprocating inopposite directions alternately stretch the fabric in oppositedirections diagon ally and open the pile in a lateral direction and soput the fabric in a better condition for being acted upon by thebrushes.

Claims:

1. In a cross brushing machine, the combination, with a revoluble drumfor supporting and traversing the fabric to be brushed, of brushesarranged around the said drum, springs which press the brushes againstthe fabric while on the drum, and means for reciprocating the drum andthe fabric endwise of the drum.

2. In a cross brushing machine, a rotary drum around which the fabric tobe treated is traversed a series of stationary brushes spaced around thedrum and means for imparting an endwise reciprocating motion to thedrum.

3. In a cross brushing machine, a rotary drum around which the fabric tobe treated is traversed, a series of stationary brushes spaced aroundthe drum, a group of rollers through which the fabric is fed to thedrum, and means for imparting an endwise reciprocating motion to thedrum and to the group of rollers.

In testimony whereof we affix our signatures in presence of twowitnesses.
